In 1989, Mr.Tombomana finds
stones, green emerald color by moving large stones to build a tomb. A
little bit later he leaves his area of Andrambali, the discovery is
forgotten.

In 1992, some tourmalines are
found in the hand of an Indian, tradesman of Amboasary, 150 kilometers far
from there.

One Tombomana by name is back home
in 1994, he profits to take again research of tourmalines. In October
1995, the young man is in Ampamata, 190 kilometers far from there, where
he practices his job, teacher. It is at this period that the deposit of
Tsaniria is exploited, it will produce small quantities of chrome
tourmalines during two years.

This
day of July 1996, the leptinite, mother rock of the malaya, was so hard, that
hand work appeared unreasonable to its discoverers, some samples
nevertheless were extracted.

It
is in September 1998 that an éluvionaire deposit was found approximately
one kilometer far from the first. The gold rush did not last, because the thickness of the ground containing the stones was modest and the deposit
became exhausted quickly. In addition, the simultaneous discovery of
Ilakaka sapphires attracted over there people coming from all the island at
the end of 1998, the deposit was thus abandoned.

The
emerald deposits from East coast, provided qualitystones since 1975
until 1993. Their professional exploitation began in the meddle of the eighties.

The first listed discovery
was reported in 1911 by the geologist Levat. Then, during the colony, a settler called Bourgeois discreetly exploited the green stones which
with the statement of the Madagascans made his fortune. At the time of their
departure, the settlers who worked emerald mines in the area, warned the natives against the bad spirits which could be in the holes. Thus, the
gems slept within 15 years.

The
area of Kianjavato, village located near the emerald mines, is in what it
remains to the rain
forest of the East coast.
